They can just live in an aquarium with the normal pebbles on the bottom that all fish live in.
Yes!
Since fish live in water they do not need to drink it as such they simply absorb what is needed.
most of the time but with betta fish no they can live at room tepature
you need an aquarium with the thing that recycles the water so the fish can live try also putting rocks and seaweed and things like that to decorate and make the fish more comfortable
No fish I know of can live in Aquarium salt. All fish need water to live in. If you are asking if a tiger barb (Barbus tetrazona) can live if it was placed in a marine (salt water) situation, then the answer is "No. Not for more than the few minutes it would take for it to die.
No you cannot. Sharks are different from commercial aquarium fish. First they live in salt water, so you need to customize your water. Second they do not eat fish food, so you need another source of food.
Defiantly not goldfish. They produce a ton of waste and need a massive aquarium to live a long and happy life . Maybe try a betta because they do not need a big aquarium . REMEMBER all fish need a home that is clean and is maintained properly . RESEARCH FIRST !! And enjoy your new fish . X
No. Guppies need a heater, whereas gold fish will overheat. Also, they will eat the guppies.
In the aquarium were water, weed, sunfish, snails, and a neon fish.
Fish live in the water, so generally they only need food. But they get their oxygen from the water through their gills, so they will need the water to have dissolved oxygen at a proper level.
Most people consider a puffer to only be one of the Arothrons, or a porcupine puffer which all get big and need at least a 125g aquarium, however Most Toby puffers can live comfortably in a 50g aquarium.
